Nichrome power rheostats rated for more power than your fan uses could be used to control fan speed, but,
They need to be big and bulky and waste/generate heat in operation. 
I have a few, but I use them to determine the resistance needed to replace a burned out speed resistor.
I have a 100 ohm, 100 watt Ohmite power rheostat that I use to determine resistance for various speeds.
